My first experiment looks promising.
What I did was put some rye berries in a container and filled it with water, and squeezed in an unmeasured amount of Sunlight antibacterial soap (not sure how much really, but it was a good squirt, enough that I thought there was no way in hell that mycelium would want anything to do with the grains) stirred it up real good and put the lid on the container and let it sit for 24 hours. Then I poured the soapy rye berries into a strainer and tossed them around a bit to drain them. Loaded a quart jar with the soapy rye berries, put on a lid with polyfil, covered with tinfoil and put it in a pot with a couple paper towels on the bottom. I then put enough water in the pot to bring the water level up to cover 2/3rds of the jar. I brought the water to a boil and turn the heat down enough so it was a slow boil, put a lid on the pot and let it go for an hour and a half. The next day I inoculated the grain with an LC I had and that jar is growing healthy myc with no sign of contams.
Pretty cool.
The idea behind this is that the soap will kill bacteria and any endospores will be hatched into a world of hurt. They won't have enough time on this planet to know they even existed, let alone fuck up my grain. And mycelium doesn't seem to be affected by it, not at all, not even at a high concentration.
So far I am having 100% success, but that was only one jar.
So the experiment continues...
10 cups of rye

150 mills of soap. It's a lot, I know, and I don't know if this much is needed, but what I do know is that it wont hurt the myc.

Filled with water and stirred up real good

And it will sit like this till tomorrow night.

I plan on loading these jars and steaming them the same way I did with the first jar. I want to see if I can do this with good results consistantly. Some of the jars will be inoculated with spores to see if spores will germinate in the soapy rye. The rest with an LC .
The soap may also make for a nice addition to an LC . We will see.
Wish me luck.
